Abstract
The invention relates to a wheeled combined jet fire extinguisher which is characterized in that a wheeled cart is taken as a carrier; a gas cylinder, a water tank/ foam tank and a superfine dry power tank are arranged on the wheeled cart; the gas in the gas cylinder enters the water tank/ the foam tank through an air relief valve and a gas pipeline; the prefixed liquid of water and foam in the water tank/ the foam tank is pressed in the inlet of a jet device through a water pipeline; the superfine dry powder in the superfine dry powder tank enters the inlet of the jet device through a powder discharge valve, a dry powder pipeline; and the water and the superfine dry powder are jet out simultaneously. According to the invention, the water and the dry powder are organically combined, thus achieving compatible properties and complementary advantages. The wheeled combined jet fire extinguisher has extremely fast speed of extinguishment, and extinguishes fire almost instantly within a certain range.
Description
Technical field
The invention belongs to fire fighting extinguisher, particularly a kind of wheeled combined jet fire extinguisher.
Background technology
Existing fire-fighting technique generally adopts the extinguishing chemical fire extinguishings such as water, foam solution, dry powder, by the single-pipeline conveying extinguishing agent to spray gun or big gun, the extinguishing chemical that ejects becomes the nature physical state, that is: water becomes water column or spray water, foam solution becomes natural shaped regular-type foam by contacting with atmosphere, and dry powder is directly injected to the scene of fire.
Existing cart type extinguishing device generally adopts the extinguishing chemicals such as water, foam solution, dry powder to pass through the single-pipeline conveying extinguishing agent to injection apparatus, no matter is that water, foam, dry powder all are to adopt single extinguishing chemical fire extinguishing.
Along with social shaping of technology, we find two or more extinguishing chemicals are ejected the formation compound fire-extinguishing agent simultaneously, have higher fire-fighting efficiency, particularly for petrochemical industry fire, electrical fire etc., the composite fire extinguishing technology demonstrates its fire extinguishing advantage more.Compound jet ejecting extinguishing technology refers to take high-velocity flow as carrier, and water and foam premixed liquid and hydrophobic ultra-fine dry powder are penetrated through combustion zone, rapidly fire extinguishing simultaneously from spray gun.And how multiple extinguishing chemical is ejected into the scene of fire simultaneously, just become a technical barrier.The particularly injection of powder extinguishing agent, because dry powder is solid, light specific gravity, particle is thin, thereby jet length is near, can not satisfy the requirement of jet length in a lot of scenes of fire, and this is restricted with regard to the application that makes dry-chemical fire extinguishing.
Utilize the attached wall effect of direct projection current, attack the hydrophobic ultra-fine dry powder of high-efficiency fire-extinguishant directly burning surface take it as carrier.Water has powerful cooling effect, and red-hot burning surface is with aqueous vapor, and the steam of formation has again very large latent heat amount, but fast cooling, but the steam concentration of the percentage of decrease fuel gas in the combustion zone again simultaneously is conducive to fire extinguishing.
Foam has the effect of very strong inhibition category-B fire, can improve blow-off velocity.
About ultra-fine dry powder: the dry powder that particle diameter is not more than 5 μ is called ultra-fine dry powder, in the mode of " gas-powder " jet ultra-fine dry powder extinguishing agent is penetrated, and forms the cold aerosol fire extinguishing agent jet.The density of cold air sol and air approach, and have the typical feature of the gas extinguishing agents such as compressibility, flowability, dispersivity, can fill the air fast the fire extinguishing effect that produces " total flooding " to the indoor confined space, and flame is extinguished in the short time at the utmost point; Can replace supplemental air flow to enter in the complex spaces such as tunnel, ancient building puts out big fire wherein.When cold aerosol fire extinguishing agent being injected in the imflammable gas that leaks out with inerting concentration, can suppress the generation of detonation detonation.
Summary of the invention
The object of the present invention is to provide a kind of wheeled combined jet fire extinguisher, by combined jet fire extinguisher water, ultra-fine dry powder are ejected simultaneously, can greatly improve the extinguishing property of fire fighting truck.
The technical solution that realizes the object of the invention is: a kind of wheeled combined jet fire extinguisher, take go-cart as carrier, in go-cart gas cylinder, water/foam tank and ultra-fine dry powder tank are set, gas in this gas cylinder enters water/foam tank by pressure-reducing valve, air delivering pipeline, water in water/foam tank and foam premixed liquid are pressed into the entrance of injection apparatus by hydraulic pipeline, ultra-fine dry powder in the ultra-fine dry powder tank enters the entrance of injection apparatus by powder output valve, dry powder pipeline, by injection apparatus water and ultra-fine dry powder are ejected simultaneously.
The present invention compared with prior art, its remarkable advantage: the organic assembling of (1) water and ultra-fine dry powder, accomplished that performance is compatible, have complementary advantages.Its blow-off velocity is unusual fast, within the specific limits, almost is the moment fire extinguishing.(2) anti-resume combustion effect is splendid, is that present any extinguishing chemical can not be compared.(3) all applicable to the confined space and infinite space.(4) truly environment-friendly type fire-fighting technique, almost without fall-out, the glassy cover layer that sticks on a small quantity red-hot surface is very easily removed after the ultra-fine dry powder fire extinguishing.(5) compound jet is the synthetic of high-efficiency fire-extinguishant, possesses the wide spectrum fire extinguishing function, be specially adapted to put out a fire to save life and property A, B, C class fire.
Below in conjunction with accompanying drawing the present invention is described in further detail.
